SANITARY-CONTAINER CONSTRUCTION.

Application filed February 20, 1925. Serial no. 10,480.

To all whom it may concern:

Be it known that I, PHILIP KnMr'rna, a citizen of the United States,residing at Milwaukee, in the county of h lilwaukee and State ofWisconsin, have invented new and useful IHIPIOVGHIGHtS inSanitary-Container Construction, of which the following is aspecification.

This invention relates to improvements in sanitary containerconstruction.

A difiiculty experienced with containers, especially those adapted foruse in dairies, where sanitation of the highest order is required, isthe tendency of the metallic reinforced portion in the flap at the head01": said containers to corrode; Ordinarily, the type of container inpresent use merely has a flap at the head portion, the said flap beingwound about a wire reinforcing band, but not being sealed so as toprevent water or other elements from readily attacking the wire withinthe flap. Further, it the flap is soldered to the wall-of the container,the labor to accomplish this task and tne amount of solder required isoften very considerable. This corrosive action of the elements onspreading naturally destroys the wire and decreases the length ofservice of the container. Further, impurities formed asthe products ofcorrosion are often introduced into the material being handled, thusproducing a detrimental effect to the quality of the material.

Among the objects of the invention, it is contemplated to provide alealnproot joint or the fiap portion with the outer wall of the bodyportion of a container; to provide a. perfectseal for the reinforcingwire positioned within the channel groove, formed by rolling the flapportion about the body portion; and to provide a simple yet eltectiveseal between the body wall and the flap portion by means of an annularflange at the extremity of the flap portion, which flange is fastened tothe body wall by soldering or any other method.

Specifically, it is aimed to bend the extremity of. the fiap portion inparallelism with the side walls of the body portion of the container toform a sealing band.

Further, it is aimed to provide means for fastening this parallelextremity or flange of the flap with a minimum of material and labor.

Still, further, it is aimed to provide a leakproot' annular channel forretaining a wire reinforcing hand between the flap and the body portionsof the container.

Still further, it is aimed to provide a simple structural arrangement ofa container formed of stamped or seamed metal whereby the container willbe absolutely sanitary.

These and other advantages, capabilities and features of the inventionwill appear from the subjoined detailed description of but one specificembodiment in which my invention may take form, which embodiment isillustrated in the accompanying drawings, in which Fig. l is a frontelevation of the section containing subject-matter of the invention; and

Fig. 2 is a section along the lines 22 Fig. 1.

Referring now more particularly to the reference characters of thedrawing, in which but one of the possible embodiments of my invention isillustrated, numeral 1 represents the body portion of a container,which, in this case, represents; a dairy pail, although I am notlimiting myself to the specific type of container, it being well withinthe scope of my invention to include all stamped or seamed sheet metalcontainers applicable for use in creameries or other industries hereproper sanitation oit the containers in use is of the essence. .Numeral2 represents the head portion of the container, which head portion isformed by a flap portion 3, integral with the body portion, and whichflap portion is bent or rolled over the body poragainst the outerperiphery or tion to term an annular channel or 'i'ooveai. Within thischannel or groove i there is placed metallic wire or band 5, said wirebeing herein adapted for reinforcing the ead portion of the container soas to enable the container to withstand the rigor of rough handling.

The flap portion 3 has at its extremity a flange portion 6, which flangeis adapted to be bent at approximately right angles to the remainder ofthe flap portion and into parallelism with the wall 7 of the bodyportion. In this manner, an annular contact and reinforcing band isformed by the flange portion 6 of the flap which band is in closeproximity to the walls of the body portion.

To firmly seal the reinforcement 5 within the annular channel 4, theflange 6 is soldered to the side wall 7. that there is considerablesurface area of the flange 6 in contact with the wall 7, the jointformed between the two portions, upon Soldering the two portionstogether, will prevent any water or other elements from entering intothe channel 4:.

The container is equipped withthe well known wire handle member 8attachable to the brackets 9, which brackets are fastened to the sidewalls of the container by riveting or any other well known method.

Though the embodiment illustrated in the drawing indicates a sanitarydairy pail, it is within the contemplation of the inventor to includevats, barrels or any other fiuic containers wherein reinforcing meansare required, but which means, on account of their tendency to corrode,must of necessity be protected from contact with any fluids.

Further, though the specific embodiment herein shown indicates aparticular form of seal, and a circular channel for a. reinforcement, itis not intended to limit the invention to these specific details, sinceit is well within the scope of the invention to include any structuralform of channel, or groove, containing a reinforcing means, whichchannel is firmly sealed from the elements by soldering or weldingorbrazing.

Due to the fact ipvaeea While the preferred embodiment of the inventionhas been described with great detail, it is to be understood that thisis for the sake of clearness only, and does not limit the scope of theinvention as described by the annexed claim.

lVh'at is claimed is: V

A sheetmetal open top container adapted particularly to contain liquids,comprising a single blank of sheet metal shaped to constitute aone-piece conical side wall body, an annular reinforcing rod arranged atthe large end of said body and upon the exterior thereof, the said endof said body being shaped outwardly around said rod throughout thecircumference of the body and engaging with said rod, the outerextremity of said engaging portion being brought tight against theexterior conical surface of said body and providing a relatively broadflange extending entirely around and in tight engagement with the body,said flange being brazed, welded or soldered to said body throughout itsentire breadth and circumference, the distance of said flange below thetop of the container and the degree of 'c-onicity of the container wallbeing such as to require forcible crimping of-the flange against thecontainer wall and continuous welding, brazing or soldering to obtain ahermetically sealed joint.
